LT3027Dual 100mA,Low Dropout, Low Noise,Micropower Regulator withIndependent Inputs U FEATURES DESCRIPTIO â– The LT Â®3027 is a dual, micropower, low noise, low dropout regulator with independent inputs. With an external0.01ÂµF bypass capacitor, output noise is a low 20ÂµVRMSover a 10Hz to 100kHz bandwidth. Designed for use inbattery-powered systems, the low 25ÂµA quiescent currentper channel makes it an ideal choice. In shutdown, quiescent current drops to less than 0.1ÂµA. Shutdown controlis independent for each channel, allowing for flexibility inpower management. The device is capable of operatingover an input voltage from 1.8V to 20V, and can supply100mA of output current from each channel with a dropout voltage of 300mV. Quiescent current is well controlledin dropout.The LT3027 regulator is stable with output capacitors aslow as 1ÂµF. Small ceramic capacitors can be used withoutthe series resistance required by other regulators.Internal protection circuitry includes reverse battery protection, current limiting and thermal limiting protection.The device is available as an adjustable device with a1.22V reference voltage. The LT3027 regulator is availablein the thermally enhanced 10-lead MSOP and low profile(0.75mm) 3mm Ã— 3mm DFN packages. â– â– ...
